If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-photobox --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

In your project's Gruntfile, add a section named photobox to the data object passed into grunt.initConfig().

grunt.initConfig({

photobox:{

task :{

options:{

// Task-specific options go here.

}

}

},

})

Photobox helps you to not deploy any broken layout to production. It takes screenshots of you current site.

Additionally you got the feature, to keep the last photosession and to overlay old and new screenshots, to see even better if something is broken or not. BE ALWAYS SURE, THAT YOU HAVEN'T BROKEN LAYOUT THE EASY WAY.
